1. Risk of Loss: Even experienced traders can make poor decisions, leading to potential losses for followers. You should have this in mind when you decide to start copy trading, especially if you automated your account to trade whenever the expert trader trades

2. Fees and Commissions: Some platforms, especially centralized exchanges and traders charge fees for following their trades that can eat into profits. This becomes a burden for traders with low capital.

3. Over-Reliance: Relying too heavily on copy trading can prevent investors from developing their trading skills and understanding.

4. Market Volatility: Sudden market changes can negatively impact trades, regardless of the trader's expertise. This means, that a copy trader still has to Monitor the market.

Profitability Considerations:

1. Performance of the Trader: The profitability largely depends on the success of the chosen trader. It's essential to research and select traders with a consistent and proven track record. Most exchanges show trader's statistics for a long period. Use it as a guide to make decisions.

2. Risk Management: Effective risk management strategies, such as setting stop-loss orders, can help mitigate potential losses. This is important because these expert traders have big capital, and setting the same stop-loss as them can easily get a low-capital trader liquidated.
